We are experiencing a major shift in battery
technology. The last 30 years were dominated by nickel-cadmium (NiCad)
batteries. This technology kicked off the popular cordless tool
revolution and enabled people to complete tasks without being tethered
to an electrical socket.

These cordless grease guns hit the market in 1999, and their popularity has increased ever since. So much so that
many companies have now added them to their product line. There are some key features to keep in mind when
deciding which brand will work best for you.
